Yeah, that's what I was thinking.

Just to put it in perspective, I used the wrong tool to remove my cassette a couple of months ago (I had an old freewheel remover lying around, didn't realize it wasn't the same thing as a cassette remover) and ended up accidentally pulling the axle cap off and removing the freehub body from my wheel. It turned out ok (with a trip to the bike shop) but for a while there I thought I had broken my brand new powertap hub. Gave me a bit of a scare.
